To get the most out of this book

1. You must be familiar with at least the basic principles of one code language. Don't worry if you don't have any professional experience since this book will guide you step by step through each chapter to get the most out of it.
2. We recommend that you start using any Unix-based operative system (Ubuntu, Debian, and macOS). This is because it is more flexible and easy to execute tasks on Terminal.
3. You will need a lot of patience. No one is born with knowledge, so never give up if one concept or example is not clear at the first go.
4. You will also need a lot of practice. It's impossible to cover all the real-world scenarios in a book, so we recommend that you go three steps ahead and modify the examples, add additional features, and research a lot.
